I was definitely expecting that puzzle to be a bit of a challenge, because it requires a bit of a different mind set than the rest.
The brute force approach should have worked for another line, but here are some hints:
hint
The numbers are not atomic numbers in *that* sense.
hint
Think about what the word "atomic" means, its Greek root "atomos" especially.
hint
It means "indivisible", what could that mean in this context?
solutionare you sure?are you really really sure?
There are exactly two prime numbers, *indivisible* if you will, the element after it is the passphrase.
Re: your (very useful!) feedback,
Iโll look into that, I didnโt notice it looking ambiguous.
I was considering adding the 2 โ ## โ , but worried that would make it too easy, Iโll consider it.
There are ways to find it without inspecting every single frame,
for example
diffing all the frames at once in gimp, the text appeared quite clearly.
4. I'll probably update the "install instructions" to note that it is not an executable file with the next update, thanks. I also thought about making it executable by embedding a binary at the start, but that would only work for one platform.
How do I get started?
Try opening the file!
How do I do that?
You should see a single line of legible text when you open it in a text editor, but you'll want to get a hex editor to help you actually solve the first puzzle (and maybe future puzzles too).
I don't know what I'm supposed to do!
There are often little hints in the puzzle itself! For example:
Spoiler for puzzle 3
The Meta logo is supposed to tell you to look at the metadata of the image.
I don't know how to do the thing you want me to do!
Learning new things is part of the fun! Google is your friend.
Hey, this is kinda fun!
I know, right?!
